Luke 11:27-28 (ESV)
As he said these things, a woman in the crowd raised her voice and said to him, "Blessed is the womb that bore you, and the breasts at which you nursed!"  But he said, "Blessed rather are those who hear the word of God and keep it!"
The woman seeks to praise Jesus by praising his Mother Mary. I can’t ever imagine using this phrase today. Jesus doesn’t flinch. Neither will he allow such lip service praise. No, he will point elsewhere. Blessed rather are those who hear the word and keep it.
I’m always a little leary about this. When people here “keep it” they begin to think of God’s word as rules that must be kept. But the word that is used here means more to hold on to it. Bo Giertz says it means to take it seriously, to hold fast to it. In other words it means to believe it. This because, finally, God’s word is not about rules for you to follow, but about Christ who died for your sins.
